Cisco 400-007 Exam With Confidence Using Practice Dumps

A (SD-WAN):SDN principles are widely adopted in wide area networks for dynamic path selection, centralized control, and policy enforcement.

B (Mobile networks):5G and modern mobile networks leverage SDN/NFV architectures to virtualize core services and optimize resource utilization.

Other options explained:

C: Metro networks adopt SDN, but WAN and mobile are more common mainstream use cases.

D/E: Application and control network are not direct SDN network types.

The question describes a network that requires virtualization at both control and data plane levels using VLANs and VRFs. This architecture aligns with:

Path isolation (A): Achieved using VRFs and VLANs, ensuring traffic separation at Layer 2 and Layer 3 across the entire network.

Group virtualization (C): Refers to grouping users or resources (such as departments or tenants) into isolated segments that remain logically separated throughout the campus fabric.

Other options explained:

B (Session isolation): More aligned with application or session-layer security, not data/control plane virtualization.

D (Services virtualization): Typically related to virtualizing network services (firewalls, load balancers).

E (Edge isolation): Not a standard design term in CCDE.
